Legend:

On the left, we see a window drawn in '''two-point perspective'''. Notice how the height of the vertical side of the window farther away from us is shorter than the vertical side of the window closest to us? Notice how the parallel lines of the top and bottom of the window frame are converging towards the top vanishing point?

In addition of the isometric perspective, a "shelf" perspective is used, mainly in toolbar and menu icons. Unfortunately, Bluecurve is wrongly using a mix of both isometric and shelf perspective in the same toolbar.

Note that the smaller icons are not merely scaled versions of the larger icons. Due to the limitation of space in the smaller sizes, there usually is a need for a bit of simplification and tweaking. Take the time to rework the icon if needed. Make sure the image is distinguishable and not muddy. With this said, keep in mind that any new icon/logo you design will have to work (or look similar) at 16x16.

An attach point is a location (x,y) on the icon that can be used as an anchor point for attaching emblems or overlays. If no points are specified, then default positions will be used.

Attach Points is a list of points, separated by "|". The points are pixel coordinates from the top left corner of the icon, except for SVG files, where they are specified in a 1000x1000 coordinate space that is scaled to the final rendered size of the icon.
